In Howard County on Monday, U.S. Sens. Ben Cardin and Chris van Hollen headlined a town hall meeting on health care as part of an ongoing effort to hear constituent concerns and also to make sure the House GOP plan is dead on arrival.

"Don't rush this through. We've got to know what we do before we pass it," Cardin said.

"This could come down to very few votes in the House, and certainly in the Senate," van Hollen said. "As long as their plan is to destroy the Affordable Care Act, I will fight it tooth and nail."

The audience was primarily composed of health care professionals. The senators said they are frustrated with the lack of specifics on the Republican health care bill, especially with talk of last-minute changes to the measure.

"We don't even know what the final version of the bill is going to look like. The Congressional Budget Office has told us millions of Americans are going to lose their coverage under the plan that was proposed. We need to have that analysis before they vote in the House," Cardin said.

But even with House Speaker Paul Ryan pitching the plan this week, the votes aren't there yet.

"Yes, I do believe this is a critical need for Americans," Ryan said Sunday on "Fox News Sunday."

Criticism of the bill is also coming from the GOP, like from Maryland's 1st District Rep. Andy Harris. The Republican told 11 News in a phone call on Monday why he's a "solid no" on the bill "as-is."

"I'm not going to vote for the bill unless there's some more changes made that take down the cost a little bit and make sure we're going to be able to bring down the premiums quickly," Harris said.

President Donald Trump plans to visit Capitol Hill on Tuesday to pitch House Republicans in person, urging them to help pass the bill.
